There are several ways in which the touch panel/cover lens assembly can be integrated with the display. The most popular option is optical bonding. Using an optical adhesive between the touch sensor and the LCD reduces internal reflections, limits parallax effects, increases the brightness of the displayed image, and enhances durability. Optical bonding can either be a dry film material that is adhered by applying pressure, or a wet material that is cured typically with UV light. The choice of dry or wet bond depends on the design of the LCD. Dawar will choose the best bonding material and method based on your particular sensor and LCD design.
The advantages of optical bonding include:
Another option for integrating your touch/cover lens assembly to the LCD is to use a gasket around the perimeter of the LCD. This method, known as tape attach, is more economical than optical bonding. Tape attach provides a reliable bond for most applications. Even though the optical performance is reduced compared to optical bonding, tape attach works well with smaller displays and indoor applications.
